Morris dancers, similar to these Leicester Morrismen dancing in Newtown Linford in 2010, may stage flash mob-style protests after being left out of the opening ceremony, The Daily Mail reported. Morris dancing stretches back some 600 years, but its origins are obscure.

Any sports enthusiast looking forward to the spectacles of Usain Bolt on the track, LeBron James on the court and Alex Morgan on the soccer field might be somewhat discouraged by all this negativity.

'It's cathartic'But Peter Catterall, lecturer in history at Queen Mary, University of London and editor of the journal National Identities, told msnbc.com that this would be a "cultural misreading" of the current outbreak of moaning.

"I think it reflects, if you like, a national history," he said. "The national narrative is often about making the best of heroic defeat, like [the Second World War evacuation of] Dunkirk and so on. The national experience in Britain is not one that's tended to create a sense in which you can just 'seize that hill.'"

"There's a tendency to think in terms of what could go wrong, rather than what could go right," he said. "It's a kind of low-level grumbling amongst people who are often quite good at grumbling. I think also people quite like grumbling, it's cathartic."

Olympic organizers may even have taken this into account in their planning.

"I do think in part the public authorities have been trying to get the moaning out of the way early," Catterall said, although he added that this "may well put off some visitors."

An age-old attitude?This kind of attitude may go back at least as far as what was arguably the world's first international event for the masses, London's Great Exhibition of 1851.

It was essentially a trade fair showing off the best products from across the world -- exhibitors included China, Persia (now Iran), the United States, India, Tunisia, Philippines and many European countries -- and it attracted more than 6 million visitors during its five-month run.

Will Brits start celebrating the Games when they actually begin? A man sits in the Atlas cafe in Leyton near the Olympic Park in London, England, on March 22, 2012.

However, in the run-up to the exhibition, Londoners expressed a string of complaints and worries that are notably similar to the current ones about the Olympics.

"I think there was a parallel in terms of all these fears," Michael Leapman, author of a book about the Great Exhibition, called "The World for a Shilling," said.

The prospect of hordes of visitors sparked alarm about congestion -- and as it turned out there were some traffic jams of the horse-and-carriage variety -- and the spread of disease, Leapman told msnbc.com.

And while tickets could be bought for a shilling, prices were increased at the weekends and other times to enable the wealthy to enjoy the exhibits without rubbing shoulders with the "hoi polloi," he added. Leapman said the author Charles Dickens was on a committee to represent the interests of working-class people, but the exhibition's organizers paid so little attention to it that Dickens quit.

Security was another big concern, with the event coming not long after several European revolutions in 1848 and amid unrest associated with the working-class Chartist movement in the U.K.

"The Duke of Wellington [a national hero after his victory over Napoleon at the Battle of Waterloo in 1815] wanted to put a troop of cavalry into Hyde Park, but the government said that would be a bit too provocative," Leapman said.

The government also attempted to set up a register of accommodation with set prices, but Leapman said most landlords resisted signing up, trusting the free market to give a better return.

'Enthusiasm'But the generally positive outcome of the event gives Leapman, who has tickets to watch hockey, some comfort amid all the present-day moaning.

He said that while there might be "some inconvenience" during the Olympics "I have a feeling it will be a great success, partly judging from the Great Exhibition."

And so the views of Hugh Robertson, the U.K. government's minister for sport and the Olympics, should perhaps not be viewed with the usual British cynicism toward politicians.

"My experience of the Games across the country has been one of fantastic support and enthusiasm," he told msnbc.com in a statement, noting the "huge demand" for tickets.

"The Royal Wedding showed that Britons know how to get behind national events, and London 2012 will be the chance to do that on a giant scale," Robertson added. "We [are] determined that everybody who comes to London for the Games has an amazing time."

John Powell, chairman of leading athletics club Belgrave Harriers, is exactly the sort of person who should be bursting with enthusiasm for the Games.

He will carry the Olympic torch and is the coach of sprinter James Ellington, who is a medal prospect for the U.K. if he makes it through the trials.

Powell told msnbc.com that he was "very excited" about carrying the flame; and it would be "amazing" to coach an athlete to a medal, the "pinnacle" of his 36 years of coaching.

But even he has a gripe.

If Ellington wins gold, Powell, his coach of some 13 years, will watch his triumph on television because, he said, he and many other coaches will not be given access to the stadium, a decision he described as "shambolic and a scandal."

"That really does take the edge of it from my point of view," Powell said.
